The Thinnest Samsung Smartphone Yet: The Story of the Galaxy S25 Edge

Samsung Electronics of South Korea has introduced a new smartphone—the Galaxy S25 Edge—that makes a striking first impression with one standout feature: its thickness, or rather, the lack of it. Lee Ji-young, Executive Vice President of Samsung’s design team, described it in one sentence:

“A model that strips away the unnecessary and completes the most essential form.”

Its slim and lightweight appearance is further accentuated through harmony with color, material, and finishing (CMF). The side frame is made of premium yet durable titanium, reinforcing the design identity of the Galaxy S25 Ultra while conveying trust in a product that is both thin and solid.

The color palette also emphasizes the slim silhouette of the Edge model while maintaining the S25 series’ signature “Luminous Shades” concept, inspired by a spectrum of light. Featured colors include Titanium Silver, Titanium Icy Blue, and Titanium Jet Black.

In addition, the “One-Mass” design, where the frame and back cover seem to form a seamless body, along with slimmer bezels, enhances the sense of visual unity and further emphasizes the slimness.

Hyungshin Park, Executive Vice President in charge of CMF design, explained:

“We considered not just color weight and saturation, but also material harmony, user preferences, and mass production processes. Within the unified CMF framework of the S25 series, we clearly expressed the Edge’s symbolic slimness and refined individuality.”

So what exactly is the “Essential Design” philosophy that Galaxy aims for? It’s not mere minimalism, but a user-centered design based on intentionality.

Lee stated, “Instead of asking, ‘How do we make it thinner?’ we asked, ‘What new value does a slim smartphone offer to users?’” She emphasized that beyond first impressions, Samsung focused on ergonomics and tactile satisfaction—how the phone feels in the hand.

Under the aesthetic theme of “Ultra Modern, Ultra Sleek Design,” this slim form factor has become a key element that enhances practical usability. “The Galaxy S25 Edge offers a snug grip in one hand, reduces wrist strain during extended use, and enhances content immersion with its narrow bezels,” said Lee.

She also shared hidden details regarding grip design:

“The front was designed to be flat, while the back has a subtle curvature—providing a comfortable grip when held.”

Lee emphasized that the design needed to balance both the ultra-slim form and the powerful 200MP camera. “We used the same CMF for the camera bump as the rear glass, making the camera appear naturally integrated. The ‘Linear Camera’ layout, a signature of Galaxy design, places the cameras in a clean vertical row,” she explained.

CMF execution required an extremely high level of precision. Park said,

“To adapt the S25’s CMF concept onto thinner glass, we worked with various departments and tested numerous color combinations and layering techniques until the final release.”

As a result, the Galaxy S25 Edge achieves a premium look and feel—with subtle yet deep glossiness—even within its slim form factor.

With its astonishing thinness, the Galaxy S25 Edge sets a new benchmark for slim smartphones. As anticipation builds, all eyes are on how the slimmest Galaxy ever will reshape the smartphone landscape—and what differentiated experiences it will offer users.
